    简介:FRED作为COM组件可以实现与Excel、VB、Matlab等调用来完成庞大的计算任务或画图,本文的目的是通过运行一个案例来实现与Matlab的相互调用,在此我们需要借助脚本来完成,此脚本为视为通用型脚本。 P[oB'  
     #7"5Y_0-  
    配置:在执行调用之前,我们需要在Matlab命令行窗口输入如下命令: _)" 5 gv  
    enableservice('AutomationServer', true) iW$i%`>  
    enableservice('AutomationServer') ^Wz{su2  
    %6:2cR  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 8rNxd=!

    在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: > n\ Q [W  
    1. 在FRED脚本编辑界面找到参考. CI{TgL:l  
    2. 找到Matlab Automation Server Type Library '(>N gd[  
    3. 将名字改为MLAPP -e\kIK %

    在Matlab里面有两种常用的数据发送选项PutWorkspaceData 及PutFullMatrix,PutWorkspaceData适用于存储一般的数据在工作区,并赋予其为变量,PutFullMatrix试用于复数数据。  \hc9Rk
